high Nessus Plugin ID 81835

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Multiple vulnerabilities have been discovered in GnuTLS, a library implementing the TLS and SSL protocols. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2015-0282 GnuTLS does not verify the RSA PKCS #1 signature algorithm to match the signature algorithm in the certificate, leading to a potential downgrade to a disallowed algorithm without detecting it.

- CVE-2015-0294 It was reported that GnuTLS does not check whether the two signature algorithms match on certificate import.

Solution

Upgrade the gnutls26 packages.

For the stable distribution (wheezy), these problems have been fixed in version 2.12.20-8+deb7u3.
